Title: Screen apparatus
Inventor: IWAMAE TAKEHISA
IPC: B01D33/06
Filed: 1980-01-21
Abstract: PURPOSE: To make sanitary as well as reduce an amount of a recovered excretion residue by discharging a residual excretion residue in a cage body to a screen side by switching an openable lid to permit to be able to carry out sufficient washing after crushing.  
     CONSTITUTION: When a large amount of a crude excretion residue having been washed is stagnated in the cage body 4, if the openable lid 2 is closed, flooded water from a water flooding port 1f is stopped and a water level in a water tank 1 is raised to a WL2 as shown in the figure and the excretion residue having been washed stagnated in the cage body is flowed out from a flooding out part 4a along with water and reached to a cylindrical screen 14 through the openable lid 2 to be treated. The crude excretion residue having been washed stagnated in the cage body 4 has been made light relatively by washing and, in addition, floated to an upper surface by turblent action to be flowed out from the flooding out part 4a. Thereby, when a short time is elasped, because the crude excretion residue in the cage body 4 is almost discharged, the openable lid 2 is again returned to an original position and a general operation condition is restored. Therefore, it is unnecessary to stop operation in recovering the residual excretion residue in the cage body 4 and the treatment of said excretion residue is efficiently carried out by continuous operation.

Inventor: UEYAMA YOSHIJI
IPC: F04D13/10
Filed: 1982-01-20
Abstract: PURPOSE:To prevent increase of vibration and reduction in the durability of pump shafts, by connecting pump units in a multiplicity of stages, and obtaining a required total pump head by discharging a fluid introduced into the first-stage unit from the final-stage unit. CONSTITUTION:Pump units 11A-11C are stacked in three stages by connecting them together by the intermediary of head covers 18A, 18B fixed respectively to the units 11A, 11B. In case that the apparatus is designed for two-mode operation, for instance, at 100% capacity and 60% capacity, a pump head H1 for the 100%-capacity operation can be obtained by driving all of motors 15A-15C. In 60%-capacity operation, on the other hand, the pump head at the same flow rate of a fluid to be handled can be reduced from H1 to H2 by stopping operation of the motor 15B of an intermediate unit 11B. With such an arrangement, it is enabled to reduce vibration of the shafts and to prolong the service life of bearings.

IPC: H02P6/08
Filed: 1987-01-14
Abstract: PURPOSE:To decrease the numbers of stator windings and yokes, to improve operational efficiency and to miniaturize a motor, by improving the mounting position of a position detector for changing over the conduction. CONSTITUTION:Three poles 20, 21 and 22 are provided to a stator 1 at about 120 deg. intervals. By switching the current in a predetermined direction and causing it to flow through two exciting coils 9 and 10, a rotation field is generated. A rotor 15 is of a double-pole constitution and is equipped with permanent magnets 16 and 17. The position of the rotor 15 is detected by position detectors 29, 30 and 31 arranged at 10 deg. intervals each. Based on this input a microprocessor 32 decides the polarity of current to cause it to flow through two exciting coils and outputs through a switching circuit. Since only two windings are used, the miniaturization and the lightweight making of the motor can be accomplished. As the mounting angle of a magnetism detection element is thereby decided, the efficiency will improve.
